Dual Drive fault: see DualDrive manual.Fault HistoryThe 1311 programmer can be used to access the controller’s fault history file. The programmer will read outall the faults the controller has experienced since the last time the fault history file was cleared. Faults suchas contactor faults may be the result of loose wires; contactor wiring should be carefully checked. Faults suchas over temperature may be caused by operator habits or by overloading.
